What To Do About the Jesus Fish?

My wife and I are purchasing a new (used) car soon. It’s a 2005 Honda something. I don’t care much about cars (I’m a cyclocommuter, and I only drive when my wife has a headache), and she’s handling the purchase, selection and so forth. But I learned tonight that the car has a Jesus fish on the back.

So of course my thought is, “Do those come off?”

Are they permanently attached? If I chisel it off, will my car permanently bear the outline of an ichthus?

If so, is there a better option? For instance, can I just locate a Darwin fish next to my Jesus fish on the (very rational) basis that 1+ (-1) = 0? What kind of message will that send, if not a cognitively dissonant non-message?

What do you think of the Jesus fish? If you purchased a used car bearing one, would you seek to eliminate it? What steps would you take?
